Fostering home-grown response to Covid-19: development of improved traditional herbal medicines to WHO standards

Abstract

Facing the unprecedented burden and rapid spread of the Covid-19 pandemic across the globe, responses from various regions have been exceptionally quick. Drug discovery has been essentially based on repurposing, particularly at the onset of the scourge. Several experimental models have been designed ranging from in vitro cell culture systems to nonhuman primates; however, each with advantages and limitations. It was revealed beside its detrimental consequences on health, economy and the society, Covid-19 has also provided opportunity to highlight the immense potential of traditional medicine as a valid alternative for addressing major health threat. The African traditional medicine has been instrumental for the control of the COVID-19 pandemic in the continent, in situation of extremely low vaccination coverage. For optimal and sustainable use of traditional medicine, we strongly recommend products be developed following the WHO standards, while taking into consideration sustainability, environmental protection and copyright issues surrounding the natural product-based drug research and development.
